##A clear and concise description of what the problem is. Ex. I'm always frustrated when [...]

First off, I love the project..

The default assembly names for the initial loader aka "dropper_cs" requires external customisation to modify. This dropper_cs assembly name is also present in the full implant which includes AMSI and ETW bypass in the bootstrap.
When serious blue teams are doing IR this becomes a OPSEC concern.

ETW is blocking a good job blocking the assembly names "for now" however deeper offline forensics will eventually reveal the glaring standout default assembly names.

Describe the solution you'd like

Add assembly name ##REPLACEME## functionality as with the other variables in config.yaml

Describe alternatives you've considered

Modifying binaries in dnSPy, recompiling core source and decompiling implants in IDA.
